Reverb effect in iPhone app

Question

Can anyone please give pointers how we can add re verb effect to a recording in an iPhone app?

Vocal live free on app store is a pretty good example of how I would want to include reverb effect.

Core Audio Overview in iOS documentation references reverb as an audio unit.

Any help beyond this will be helpful.

Did you look into [this](http://stackoverflow.com/questions/4750032/how-to-develop-an-iphone-app-with-reverb-functionality) and [this](http://stackoverflow.com/questions/4813746/how-to-apply-reverb-filter-or-any-other-sound-effect-to-a-wav-sound-file). It also mentions Igor's **ObjectAL** answer. — esh, Feb 14 '13 at 12:26

If you have access to the raw audio data, you can simply convolute it with corresponding reverberation finite impulse response (FIR) filter kernel.

Doesn't sound very simple without additional explanation. – Remover Nov 25 '13 at 15:58
@Remover Google for FIR and convolution. What do you expect, that I write a code in your place? – Archie Nov 26 '13 at 08:23
